Updating the BIOS with the Iflash Memory Update 
Utility 
With the Iflash Memory update utility you can update the system BIOS from a 
bootable CD-ROM, bootable USB flash drive, or other bootable USB media.  The utility 
available on the Intel World Wide Web site provides a simple method for creating a 
bootable CD-ROM that will automatically update your BIOS.  The Iflash BIOS update 
files can also be extracted locally to your hard disk drive and copied to a bootable USB 
flash drive or other bootable USB media.   
The Iflash Memory update utility allows you to update the BIOS and Intel Management 
Engine in flash memory 
 
NOTE 
Review the instructions distributed with the update utility before attempting a BIOS 
update. 
 
 CAUTION 
Do not interrupt the process or the system may not function properly. 
 
1.  Uncompress the BIOS update file and copy the .BIO file, IFLASH.EXE, and .ITK file 
(optional) to a bootable USB flash drive or other bootable USB media. 
2.  Configure the BIOS or use the F10 option during POST to boot to the USB device. 
3.  Manually run the IFLASH.EXE file from the USB device and manually update the 
BIOS. 
Recovering the BIOS 
It is unlikely that anything will interrupt the BIOS update; however, if an interruption 
occurs, the BIOS could be damaged.  Due to BIOS size and recovery requirements, a 
CD-R with the .BIO file in the root directory will be required.
